[A case of Jordans' anomaly].

A 35-years old female with Jordans' anomaly was reported. She had been treated for diabetes mellitus and hypertension at another hospital. She was admitted to our hospital for operation for diabetic retinopathy on July 9, 1992. Wright-Giemsa stained peripheral blood smear revealed multiple vacuoles in the cytoplasm of the granulocytes and monocytes. Histochemical studies of these vacuoles showed positive for Sudan III but negative for peroxidase, alkaline phosphatase and PAS staining. Electron microscopic examination revealed that lipid containing vacuoles had no clear membrane and were not associated with cell organelles. Laboratory findings of the serum showed hyperglycemia (FBS 188mg/dl), high HbA1c level (9.4%) and mild type IIa hyperlipidemia. Abdominal sonogram and abdominal CT showed no remarkable abnormalities except for mild fatty liver. Her elder sister and daughter had similar morphological findings in granulocytes, monocytes and lymphocytes.
